Ultra-realistic erotic studio photograph of a young adult woman with short, wet, dark brown hair slicked back, eyes closed in pleasure, soft full lips slightly parted, head tilted back and to the side. She is completely nude, slim athletic body with small natural breasts, soft skin with realistic texture and subtle sheen from moisture. Her left hand rests gently on the side of her neck. Legs spread wide open in a straddle pose, one knee bent, the other extended, revealing a close-up of her smooth shaved vulva with detailed labia and clitoris. A thick, transparent crystal-clear glass dildo with realistic veining and a flared base is deeply inserted into her vagina, the shaft glistening with moisture, standing upright on a highly reflective glossy white floor that creates a perfect mirror reflection of her body and the dildo. Visible tattoos on her left outer thigh and calf. Soft diffused studio lighting from above and the side, creating gentle shadows and highlights on her skin, neutral light gray seamless background. Shot from a low frontal angle looking up between her legs, high resolution, photorealistic skin pores, fine body hair details, cinematic composition, 8k quality, sharp focus on the genital area and dildo.
